NOAA data shed new light to improve NASA satellite products for carbon dioxide

New research shows that systematic errors in the OCO-2 total column CO₂ products can be large enough to confound reliable surface flux estimation.

Urban areas across the U.S. are undercounting methane emissions, a new study shows

An eight-year study of Boston’s natural gas system has revealed that emissions of methane, a powerful greenhouse gas, are significantly higher than previously estimated.

GML is granted funding to investigate COVID impacts on the U.S. non-CO2 greenhouse gas emissions

A new research initiative “Quantifying the impacts of COVID-19 on U.S. national and regional non-CO2 greenhouse gas emissions from atmospheric observations” is granted funding from Climate Program Office’s Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) program and Climate Observations and Monitoring (COM) program.

NOAA’s new uncrewed glider poised to help vastly increase high-altitude research

Scientists from NOAA’s Global Monitoring Laboratory, are fine-tuning a low-tech, cost-effective system for lifting a small payload of specialized measuring instruments to the edge of space, and then guiding it back to the launch location.

UCI researchers analyzed Antarctic air samples to learn of a 70-percent increase in atmospheric hydrogen over the past 150 years

NOAA Scientists contributed to a study by UCI researchers of air trapped in compacted layers of Antarctic ice and snow to come up with some answers and a few new questions about the amount of molecular hydrogen in our planet’s atmosphere.

First Annual Report Highlights Links Between Air Quality and Climate Change

Two CIRES scientists working in NOAA laboratories contributed to the WMO’s first-ever Air Quality and Climate Bulletin, released on September 3.

Highlights of GML’s contributions to the 2020 BAMS State of the Climate Report

Scientists from Global Monitoring Laboratory contributed to the Bulletin of American Meteorological Society State of the Climate 2020 report report as editors and authors.

A new way to measure how Arctic plant communities respond to climate change

Modeling using atmospheric measurements of carbonyl sulfide (COS) was used for quantifying photosynthetic CO2 uptake in the Arctic and Boreal ecosystems.

NOAA-NASA collaboration to study the impact of convective storms and the North American Summer Monsoon on stratospheric chemistry

Global Monitoring Laboratory and NASA team up in the DCOTSS (Dynamics and Chemistry of the Summer Stratosphere) project to study the convective impact of the North American Monsoon Anticyclone on stratospheric composition and ozone depletion.

Deforestation, warming flip part of Amazon forest from carbon sink to source

New results from a nine-year research project in the eastern Amazon rainforest finds that significant deforestation in eastern and southeastern Brazil has been associated with a long-term decrease in rainfall and increase in temperature during the dry season, turning what was once a forest that absorbed carbon dioxide into a source of planet-warming carbon dioxide emissions.

New research suggests no significant reduction in total oil and natural gas emissions from 2008 to 2016 in Weld County, Colorado

New research suggests no evident reduction in total oil and natural gas emissions and their contribution to the regional air quality from 2008 to 2016 in Weld County, in Northeastern Colorado.

Remote monitoring towers provide data that advance the understanding of boreal forest fires

Boreal forest fires influence the global carbon cycle and climate system by consuming aboveground and underground biomass and directly releasing carbon dioxide, other trace gases, and aerosols into the atmosphere. A new study with GML co-authors quantified emission factors of carbon monoxide and methane using ground-based observations from the Carbon in Arctic Reservoirs Vulnerability Experiment (CRV) tower in Alaska.

New analysis shows microbial sources fueling rise of atmospheric methane

The sudden and sustained rise in atmospheric levels of the potent greenhouse gas methane since 2007 has posed one of the most significant and pressing questions in climate research. A research team led by CIRES and NOAA scientists has tested the leading theories for surging methane levels by analyzing the stable carbon isotope ratios (δ13C-CH4) from methane captured in a large set of global air samples.

Carbon dioxide peaks near 420 parts per million at Mauna Loa observatory

Atmospheric carbon dioxide measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory peaked for 2021 in May at a monthly average of 419 parts per million (ppm), the highest level since accurate measurements began 63 years ago, scientists from NOAA and Scripps Institution of Oceanography at the University of California San Diego announced today.

GML scientists successfully test high-altitude return glider with the AirCore science package

Global Monitoring Laboratory (GML) and Cooperative Institute for Research in Environmental Sciences (CIRES) scientists successfully tested a new method for high-altitude air sampling and instrument recovery from May 13-25, 2021.
